Well, this has been more fun that I thought it would be. Unless you like cutting and grinding, don't run a mechanical fuel pump. Also send the Ford crank pulley to Larry to modify, pain to mark and get right. If the original balancer ring is there, it makes a good template. The stock top rad hose will not work and the 950K6 belt is too short. I would have to max out the tensioner to even get the belt on.get the belt on. Any tips to figure out belt length is appreciated. Would I do this again probably not. The R4 compressor was a PIA to pull the clutch and reassemble. This is no fault of Larry's, his brackets are good. I still need to make a brace for the passenger side, will definitely need the support, I can see flexing.

Good idea, there needs to be a sticky. I bent a turnbuckle I had, too long but a shorter one should line up where the old non A/C alternator top bracket bolted to the intake. Here is the belt installed, maybe the tension is OK.

What are you guys thoughts on the belt tension? I will compare to to the truck and Challenger. I picked up a couple of small turnbuckles to support the passenger side bracket. Top hose will be in Thursday. So just wire the alternator, fill the coolant and power steering and put in a battery to fire. I hope my new Remy 105 amp CS130 CS130 alternator doesn't squeak. Sounded squeaky spinning the pulley. It is supposed to new, not reman and a lifetime warranty.

Update, I found the sbc brackets need to be reamed out so they sit tight against the aluminum adapters, makes sense. Since a 9/16" drill bit is expensive and hard to find, my widest stepped drill bit worked like a charm. It makes the long, small head intake bolt I used near the fuel pump nearly to long and the outside one on the power steering/alt bracket almost the same. Everything lined up nicely and no belts jumping off at fast idle. It does make a bit of a whirring sound but nothing too loud. Now to fit the 70S rad in this car, I will need to cut the support on the passenger side to fit in the 34" wide rad. The other rad was half plugged, almost overheating without A/C and I am not paying $250 for a Spectra aluminum/plastic G body rad up here.
